Although I don't think frozen veg are as tasty as fresh veg, they are convenient and are supposed to still be nutritious. I don't think the frozen veg are very nice just steamed or boiled, but mixed with other food can be okay. I do tend to use them when on caravaning holidays.
You are no doubt well aware of easy ways to incorporate more veg into your diet, but just in case you have not thought of them...
For quick and/or easy ways to have veg:
- mix a couple of cups of frozen mixed veg, best quality and variety you can find, into a meat sauce
- fry some onions with curry powder or soy sauce, or whatever flavoring you like then add the 2 cups of frozen veg and maybe some pre cooked rice/quinoa mix
(When doing a curry, I do boil some potato and sweet potato separately at the same time (usually start it a bit earlier) then add that, with its liquid, to the curry.)
- use pre made stock with a soup mix (beans, lentils etc) and add in as many veg as you like to make a soup. Purée when cooked and freeze the extra. Sprinkle some cheese over before eating.
Many forum members have posted easy tasty veg recipes over the years. I do think it is worth the effort of incorporating more veg into your diet.
Fruit is good, but it is high in sugar, so ideally we shouldn't have too much. Two serves a day, apparently. I used to have more like 10 serves a day, which was one reason I was overweight! Generally I will have 3-4 serves a day tho, as I love fruit.
Good luck with finding something that works for you.
